Hi all;
I would like to generate a discrete-time time-varying multipath (doubly selective) channel. How can I do that? Also, I need the powerdelayprofile of the multipath channel to decay exponentially. Any help will be highly appreciated.
Thanks

Hi all,
I'm measuring the frequency response and calculating the powerdelayprofile. In between the transmitter and receiver, i kept the box with water(level-24cm). I'm measuring in indoor environment and also in Anechoic chamber. I calculated the rms delay spread for both cases. Indoor environment has 22ns rms (...)

I think I need to narrow down what I want to do.
Today I thought may be I should simulate powerdelayprofile as a fingerprint for my indoor localization project, using a ray tracer.
I found a ray tracing tool written in Java, called RAPSOR, in Sourceforge.
Unfortunately, I could not make it work (it needs netnbeans) and there is no (...)

Hi,
I have some channel measurement data obtained in frequency domain using vector network analyzer. I would like to plot the powerdelayprofile(PDP) of this data in Matlab. Can anyone tell me how to do this??
It is urgent...
help please...

Is the powerdelayprofile dependent on the carrier frequency?
I have read in many books that the delay spread for outdoor environment is in the order of 1 us. But that is for carrier frequency of around 900 Mhz. (cellular communication). I need the powerdelayprofile (...)

Hello Everyone.
I´m computing a FDTD simulator to study the radio channel characteristics using powerdelayprofile. I use a scenario 2550px x 2550px and I need more than 2 hours to have some kind of results. I´m reading about parallel computing with parallel computing toolbox and I tried some stuff...without good results...
Tried to (...)

Hello all.
I'm working on FDTD + CPML and for now my objective is to plot the powerdelayprofile or for other words a graph with time in order of power.
I´m using TEz mode.
The manner that I´m calculating the power in dBW is:
10log(((Ex^2+Ey^2)*lambda^2*1)/(120*pi*4*pi))
where I admite that (...)

The powerdelayprofile from the original document for the PEC situation, the power is almost always at the same level (for example the multipath components are almost always in 12dB) , and in my simulation, the power is always decreasing with time.
What kind of excitation do you use? If you use a (...)

Would anyone please have any idea about how to find the h values of a channel when you know the powerdelayprofile of this channel
I have tried using the rayleighchan and filter commands I dont know how to find the h though which one is which. I have a 6 ray model
Please help
